I agree with Lorne but on his lower end and yes I too agree the case is correct, redone inside.
The color case harden colors don't look correct. Especially when compared to the trigger bow photo. The colors look to be heat induced, i.e. like someone took a torch to it to give it some color.
I'd venture to say based on the comparison photos again of the trigger bow and those of the underside of the stock forend, that the barrels have been redone. With the amount of wear that some of the photos show of the stock, the barrels would be worn at muzzles and especially worn where the forehand is in contact. They have a nice pattern though.
The locks are 3 pin bridal and are probably very nice inside - I hope.
Bring it to the Nationals at Friendship in June and we'll shoot it all day!
Looks like a good solid shooter!
Thanks
